| Base Table | assoccoo |
| Attribute Name | orid |
| ColumnName | orid |
| Logical Rolename | |
| RoleName | |
| Definition | Origin identification. Each origin is assigned a unique positive integer which identifies it in the database. The orid is used to identify one of the many hypotheses of the actual location of the event |

| Attribute Name | commid |
| ColumnName | commid |
| Logical Rolename | |
| RoleName | |
| Definition | Comment identification. This is a key used to point to free-form comments entered in the Remark relation. These comments store additional information about a tuple in another relation. Within the Remark relation, there may be many tuples with the same commid and different lineno, but the same commid will appear in only one other tuple among the rest of the relations in the database |
| Note | Range: commid > 0 |
| auth |

| Attribute Name | subsource |
| ColumnName | subsource |
| Logical Rolename | |
| RoleName | |
| Definition | A second identifier to specify the system or process that derived the data. e.g., the origin's AUTH is CI, but the subsource (the solution) was computed by JIGGLE |
| Note | Range: Any free-format string up to 8 characters |
| delta |
| Base Table | assoccoo |
| Attribute Name | delta |
| ColumnName | delta |
| Logical Rolename | |
| RoleName | |
| Definition | Source-receiver distance. This attribute is the arc length, over the earth’s surface, of the path the seismic phase follows from source to receiver.

| Note | Range: delta >= 0.0 Units: Kilometers |
| seaz |
| Base Table | assoccoo |
| Attribute Name | seaz |
| ColumnName | seaz |
| Logical Rolename | |
| RoleName | |
